Description
The PDM34089 is a 2,097,152 bit synchronous random access memory organized as 65,536 x 32 bits. It is designed with burst mode capability and interface controls to provide high-performance in second level cache designs for x86, Pentium, 680x0, and PowerPC microprocessors. Addresses, write data and all control signals except output enable are controlled through positive edge-triggered registers.
